To all willem it may concern.'

Be it lrnown that l, HENRY il. GAISMAN, a citizen of the United States, `and resident of N ew York city, in the county of New York t and State ot New York, have invented certain new and useful Improvements in 'llobacco Fipes, of which the following is a specication.

'lhe object ot my invention is to provide a ie tobacco pipe having simple and eflicient means to enable the smoke passageway to be readily blown out, or cleaned by passing any suitable cleaner through it, without requiring the stem to be removed from the bowl, le and to maintain tight joints while the pipe is being smoked.

ln carrying out my invention l provide a body having a bowl for' the tobacco and a duct communicating with the bowl, a stem ao having a Ibore and provided with .an extension rotative in said duct, said extension having a longitudinal passage or channel communicating with the borel in the stem, said body having van outlet bore communi- 25 eating with said duct, said extension being adapted to close said bore when the stem and extension are in the smoking position, said stem and kextension being rotative to present said channel or passage in comto munication with said outlet bore when the stem is to be cleaned, whereby the user may blow through the stem and extension to expel nicotine and other accumulation from the stem and extension, or may pass a te' cleaner through the same, at which time the extension will close the communication between the bowl and said duct.

Reference is to be had to the accompanying drawings forming a partv hereof, to wherein Fig. l is a plan view of a tobacco pipe embodying my invention;

Fig. 2 is a section on line 2, 2, in Fig. l showing the parts in position tor use;

Fig. 3 is a cross section on line 3, 3, in Fig. 2;

Fig. t is a view similar to Fig. 2, showing parts in position for cleaning; and

Fig. 5 is a section on line 5, 5, in Fig. d. 'Similar numerals oli reference indicate corresponding parts in the several views.

The numeral l indicates the body oi the pipe which may be provided with any suitable tobacco bowl or recess 2, said body havtl ing 'a duct at 3 in communication with the howl at d, and at `5 is .the stem of the pipe.

dit

Said parts may be of any usual and desired material and construction, the stem being shown provided with a reduced portion 5 rotative in duct 3 in.`vany ordinary t0 way: The stem 5 is provided with an extension 6 axially disposed respecting said stem and snugly fitted to rotate within the duct 3, the inner end of said extension being shown located at the point of communication t5 a between the bowl and the duct; 'lhe'extension 6 may be ot' any suitable material and secured to stem 5 byany desired means,

or may be integral with said stem. 'llhe bowl is provided with an outlet or discharge 'Z0 bore 7 communicating and in-register with duct 3-below the bowl. The stem 6 has a longitudinal channel or passage 6a which communicates with the bore 5b in stem 5 and is adapted to communicate at its inner end 75 with the bowl at the point l and also with the bore 7 according to the position of the stem in respect to the bowl. For convenience of manufacture and use the channel or passage 6 is shown tormed in one vside of eo extension 6 so that said channel is at one side of the longitudinal axis of extension 6, and the bore 7 is on the "opposite side of said axis. rllhe bore 5a oli stem 5 registers with the channel 6a that is disposed eccentrically et respecting extension 6. When the parts are in the position shown in Fig. 2 the channel 6 will communicate with the bowl for smohn ing and the adjacent'end of extension 6 will close the bore 7, and when the parts are in oo the position shown in Fig. 4 the extension 6 will obstruct communication between the bowl and duct 3 and the channel or passageway 6 will be in communication with the bore 7 for cleaning. The innerend of eX- e5 tension 6 and the adjacent end wall 3a o the duct 3 at the inner end of bore 7 are shown located transversely respecting the axis ot the stem and abut, having smooth cooperating surfaces serving inthe nature of a valve me to obstruct or close bore k7 when the parts are in position for smoking to prevent lealiage of nicotine, moisture and the like through said bore and to obstruct the entrancel of air through the' bore during smolr- 105 ing. ln other words, the channel 6 communicates with the bowl and extension 6 closes duct 7 simultaneously.

lll/Then the parts are in the position shown in Fig. 2 the pipe may be smoked in an orilo dinary way, the smoke traveling from the bowl through channel or passage' 6 and through bore 5". When the user desires to clean the pipe he will rotate the stem and its extension 6 until the channel 6 registers with bore 7, whereupon, since the channel will be out of register with the bowl, he may blow through the stem and the extension to blow any nicotine, moisture, accumulated tobacco, etc., through the outlet bore 7, or he may run a cleaner through the bore 5b, channel 6a and bore 7 and then restore the stein and extension to position for use. By means of m improvementsa tobacco pipe may be rea il kept clean 1n its passages without requirlng the stem to be removed and without soiling the fingers, which lfrequently occurs where the stems of pipes are removed in order to clean the stem and the duct communicating with the bowl.

Having now described my invention what I claim is 1. A tobacco pipe comprising a body having a bowl and a duct communicating therewith, a stem. rotatively fitted to the body and provided with a bore andan entension having a channel communicating with said bowl and adapted to register with the bowl, said body having an outlet bore communicating with said duct adapted to communicate with said channel when the stem is out of smoking position,

2. A tobacco pipe comprising a body having a bowl and a duct communicating therewith, a stem rotatively fitted to the body and provided with a bore and an extension having a channel communicating with said bowl and adapted to registerwith the bowl,

said bodyhaving an outlet bore communieating with said duct adapted to communicate with said channel when the Stem is out of smoking position, said extension having an inner portion in position to obstruct .communication between the duct and the bore when the stem is in one position and.

having a portion to obstruct communication between the bowl and the duct when the stem-is in another position.

3. A tobacco pipe comprising a body having a bowl and a duct communicating therewith, a 'stem rotatively fitted to the body and provided with a bore and an extension having a channel communicating with said bore and adapted to register with the bowl, said body having an outlet bore communicating with said duct adapted to communicate with said channel when the stem is out of smoking position, said duct having a smooth inner wall adjacent to the inner end of the bore, said stem having a smooth` inner end cooperative with said Wall to obstruct the passage through the bore when the stem is in smoking position.

4. A tobacco pipe comprising a body having a bowl and a duct communicating therewith, a stern rotatively fitted to the body and provided with a bore and an extension having a channel located eccentrically along a side of the stem, said channel communicating with said bore, said channel adapted to communicate with the bowl, the body having an outlet bore communicatin with said duct, said extension closing sai bore and said channel communicating with the bowl simultaneously.
